Definitions

  • the present invention relates to a temperature control system for influencing a temperature in at least one room of a building, the temperature control system comprising at least two heat exchangers, each heat exchanger having a control valve, a supply port and a return port, the ports being connected to a fluid supply system supplying a heat carrying fluid, a sensor arrangement detecting at least one physical characteristic of the heat carrying fluid at each heat exchanger and at least an additional physical characteristic of the system, the system further comprising processing means receiving data from the sensor arrangement, wherein the processing means comprise diagnostic means detecting a kind of a malfunction of the temperature control system.
  • the system can be used for heating or for cooling the rooms of the building.
  • the heat carrying fluid is of elevated temperature, for example hot water of 50° C to 70° C.
  • a similar or the same system can be used for cooling the rooms.
  • the heat carrying fluid has a temperature below 20° C.
  • the object underlying the invention is to facilitate finding of a defect in a temperature control system.
  • processing means detect a wrong size of a heat exchanger when at least one of the following conditions are fulfilled:
  • the processing means already receive data from a number of sensors of the sensor arrangement. These data show a state or a picture of the system. If this state does not match a predetermined state, there is not only an error. It is also possible to detect a kind of the error or a kind of a malfunction. For example, clogging of a heat exchanger will give a combination of physical characteristics different from a fault in the source of the heat carrying fluid.
  • the processing means use the diagnostic means which can be realized by hardware means or by software functions or by a combination of hardware means and software functions. A situation in which the heat exchanger has a wrong size can occur not only after the first construction of the building, but also after changes in the building. In office buildings it is possible to move walls between rooms and to change the size of the rooms. In such a case it is possible that a room becomes too large for the heat exchanger.
  • the physical characteristic of the heat carrying fluid is an outlet temperature at the heat exchanger.
  • the outlet temperature at the heat exchanger shows whether the heat exchanger has thermal energy exchanged with the room.
  • the physical characteristic is a difference between an inlet temperature and the outlet temperature. When, for example, both temperatures are almost equal, this is a clear indication that the heat exchanger does not work correctly.
  • the additional physical characteristic of the system is an opening degree of at least one of the control valves.
  • the opening degree can, for example, correspond to other characteristics for example the room temperature or the outlet temperature. If this is not the case, this could be an indication that a fault in the control valve has occurred. It is possible, for example, to measure the opening degree of the control valve. It is also possible to use an information about a commanded opening degree of the control valve.
  • the processing means process the physical characteristics over a predetermined time. In other words, the processing means do not immediately react after a change in the physical characteristics.
  • the processing means wait, for example, whether a stable condition will come out. If the physical characteristics in this stable condition do not match the desired values, this can be an indication of the kind of error.
  • the processing means compare at least one of the physical characteristics with an expected value.
  • the expected value is based on at least one other physical characteristic.
  • the control valve is opened or the control valve is commanded to be open and the outlet temperature does not change accordingly, this is an indication that the heat exchanger has been clogged or that the valve does not work correctly.
  • the processing means detect a bad pipe insulation if at a predetermined difference between inlet temperature and outlet temperature the inlet temperature of heat exchangers in the systems varies more than a predetermined range.
  • a heat exchanger near the source of the heat carrying fluid receives a heat carrying fluid with a much higher temperature than a heat exchanger remote from the heat carrying fluid source this is a clear indication that some heat has been lost on the way.
  • the processing means are distributed in the system. Accordingly it is not necessary to use a single central unit to receive all data, although this is of course possible.
  • the processing means can be formed by a number of units which are connected by a network.
  • control valves are controlled by actuators and at least two actuators form a part of the processing means.
  • Each actuator has its own control means to control the position of the control valve.
  • These control means usually receive data, for example from the room temperature sensor to make it possible to adjust the control valve in such a way that the heat exchanger outputs enough heat to reach the room temperature set point. Since such data are already available, the different control units in the system (for example in each actuator) can decide what they want to contribute with in relation to the overall task needed for diagnostic. One controller function can then do the overall evaluation and receives already partly evaluated data from the other controllers and then, for example, send out a message that a problem exists in the system and what kind of problem it is.
  • the processing means detect a malfunction when a combination of a low temperature set point and a low delta T in one room and a higher temperature set point and a higher delta T in a neighbor room occurs.
  • the delta T is the temperature difference between the inlet temperature and the outlet temperature of a radiator.
  • the invention is explained in the following in connection with a heating system. However, it can be used as well in connection with a cooling system.
  • the system comprises two rooms 2, 3, which belong to a building.
  • the first room 2 there are two heat exchangers 4, 5, whereas in the second room 3 only one heat exchanger 6 is mounted. It is possible to consider apartments instead of rooms 2, 3.
  • the heat exchangers 4, 5, 6 can be, for example, in form of radiators.
  • the heat exchangers 4, 5, 6 are connected to a supply line 7 and to a return line 8.
  • the supply line 7 is connected to a source 9 of a heat carrying fluid, for example hot water.
  • the source 9 comprises a boiler 10 and a pump 11.
  • the boiler 10 the heat carrying fluid is heated.
  • the pump 11 is used to drive the heated fluid through the supply line 7 to the radiators 4, 5, 6.
  • the return line 8 connects an output of the heat exchangers 4, 5, 6 again back to the source 9 and to the boiler 10.
  • the first room 2 comprises a room temperature sensor 12.
  • the second room 3 comprises a room temperature sensor 13.
  • the heat exchanger comprises a first inlet temperature sensor 14 and a first outlet temperature sensor 15.
  • the second heat exchanger 5 comprises a second inlet temperature sensor 16 and a second outlet temperature 17.
  • the third heat exchanger 6 comprises a third inlet temperature sensor 18 and a third outlet temperature sensor 19.
  • the first heat exchanger 4 is connected in series with a first control valve 20.
  • the first input temperature sensor 14 is mounted between the first control valve 20 and the first heat exchanger 4 or in an actuator 24 of the first control valve 20.
  • the second heat exchanger 5 is connected with a second control valve 21 in series. Again the second input temperature sensor 16 is mounted between the second control valve 21 and the second heat exchanger 5 or in an actuator 25 of the second control valve 21.
  • the third heat exchanger 6 is connected in series with a third control valve 22 and the third input temperature sensor 18 is mounted between the third control valve 22 and the third heat exchanger 6 or in an actuator 26 of the third control valve 22.
  • the first control valve 20 is actuated by the first actuator 23.
  • the second control valve 21 is actuated by the second actuator 24.
  • the third control valve 22 is actuated by the third actuator 25.
  • All actuators 23-25 are "intelligent" actuators comprising an own processing unit.
  • the actuators 23, 24, 25 are mounted on the control valves 20, 21, 22. In other words, the control valves 20, 21, 22 comprise each an actuator 23, 24, 25.
  • the first room temperature sensor 12 is connected to the first actuator 23 and to the second actuator 24 so that the actuators 23, 24 can control the first control valve 20 and the second control valve 21 which in turn control the flow of the heat carrying fluid through the heat exchangers 4, 5 with the purpose that the temperature in the first room 2 reaches a room temperature set point or a desired room temperature.
  • the second room temperature sensor 13 is connected to the third actuator 25 which in turn controls the third valve 22 to reach a room temperature in the second room 3 which corresponds to a room temperature set point or a desired room temperature.
  • the temperature sensors 12, 13 are shown as separately placed sensors. However, they can be placed as well together with the actuators 23, 24, 25 or they can be integrated into the actuators 23, 24, 25.
  • the actuators 23, 24, 25 are able to detect the opening degree of the respective control valves 20, 21, 22. Furthermore, they "know" which opening degree should be reached.
  • the opening degree can, for example, be given by a control unit receiving signals from the room temperature sensors 12, 13.
  • the actuators 23, 24, 25 can be considered as valve sensor or opening degree sensor.
  • the sensor arrangement can have more or less than the sensors shown depending among others on the number of radiators and on the number of rooms to be heated.
  • the actuators 23, 24, 25 are able to react on a difference between the room temperature detected by the room temperature sensors 12, 13 and a room temperature set point. They already collect or receive data from the respective sensors. Furthermore, they can receive data from the inlet temperature sensors 14, 16, 18 and from the outlet temperature sensors 15, 17, 19.
  • the actuators 23, 24, 25 therefore form processing means receiving data from the sensor arrangement.
  • the processing means are distributed over the system. Furthermore, more control units or processing units can be provided, for example in the source 9. It is further possible to use processing units which are arranged outside of the system 1, for example in a cloud computing cluster or in a computer outside the system 1.
  • connection between the sensor arrangement and the processing means 23, 24, 25 can be made by wire or wireless. Such a connection is not shown in the drawing. However, the person skilled in the art will know how to connect sensors and actuators and the respective processing means.
  • the processing means comprise diagnostic means which are able to detect a kind of a malfunction of the temperature control system.
  • the malfunction can be a clogged heat exchanger or a stuck valve. In both cases the flow of the heat carrying fluid through the heat exchangers 4, 5, 6 is blocked or at least throttled. The result is that the temperatures measured by the sensor arrangement, in particular by the inlet temperature sensors 14, 16, 18 and the outlet temperature sensors 15, 17, 19 deviate from a normal behavior.
  • a further possibility is that the heat exchanger is too small which will be discussed below. If the inlet temperature is not considerable above the average room temperature, the heat exchanger is clogged as well. It is possible to define a first predetermined value for the difference between the inlet temperature and the average room temperature which is allowed. When the difference is larger than the first predetermined value, the system detects the error. Such an error can be indicated on a display or can be sent to a maintenance or service unit. The same is true for all other errors.
  • Another malfunction can occur, when the same temperature on inlet and outlet is detected and the temperature in the rooms does not reach the desired value. This indicates that something is not in order with the source 9. For example the pump 11 might be broken so that there is too low flow or the boiler 10 is off so that the temperature of the heat carrying fluid is too low.
  • the same malfunction is determined if the input temperature is not considerably above the average room temperature, in this case a source 9 has a malfunction.
  • the supply temperature can be too low as well.
  • Another malfunction can be that the input temperature at a certain delta T on the heat exchangers 4, 5, 6 in the system 1 varies (more than an allowed range). This is a clear indication that the line losses are too high and a better insulation would be necessary.
  • a still further malfunction can be that the same temperature is detected at the inlet and the outlet of a heat exchanger 4, 5, 6 and at the same time the room temperature in the room 2, 3 is too low. In this case the heat exchanger is too small.
  • a further malfunction can be that a combination of a low temperature set point and a low delta T in one room 2 (or apartment) and a higher temperature set point and a higher delta T in a neighbor room 3 (or apartment) occurs. In this situation an alarm should be produced that one room 2 needs to change the temperature set point in order not to heat up the room 3 next door or neighboring apartments.
  • the delta T is the temperature difference between the inlet temperature and the outlet temperature.
  • a low delta T means that only few heat is radiated from the heat exchanger 4, 5, 6.
